An electric bicycle comprises a frame with a plurality of frame tubes (120), wherein a drive battery (250) accommodated in one of the plurality of frame tubes (120). The bicycle comprises a sleeve (300) accommodated in the one of the plurality of frame tubes (120). The sleeve (300) has a shell surface with an outer geometry adapted to an inner geometry of the frame tube (120), such that a radial position of the sleeve (300) with respect to the frame tube (120) is fixed, and an inner surface adapted to an outer geometry of the drive battery (250), such that a radial position of the battery (250) with respect to the sleeve (300) is fixed. The drive battery (250) is accommodated in the sleeve (300). The sleeve (300) provides an interface between the battery (250) and the frame tube (120). It helps to compensate manufacturing tolerances, improves the support of the battery (250) within the frame tube (120) and/or facilitates the insertion and removal of the battery (250). Furthermore, the same battery type, having a given geometry, may be accommodated within frame tubes having different geometries.
